It's pointless if you have a pc. If you have a pc and still got one, well ps4 and switch are the choices you should have made, they actually offer something different.
Negative.
Too many people can't afford a good gaming PC so the huge majority are still on console. This means that if you want to play games like Call of Duty for Online Multiplayer you are pretty much stuck playing on PS4 or Xbox One if you want a decent amount of people to play with. Many games like that still suffer having a very low amount of players on PC platform.
